Herkenrode Abbey () was a Catholic monastery of Cistercian nuns located in Kuringen, part of the municipality of Hasselt, which lies in the province of Limburg, Belgium. Since 1972 some of the surviving buildings have served as the home of a community of the Canonesses of the Holy Sepulchre, who have since built a new retreat center and church on the site. In 1974 the buildings and the surrounding estate were designated and since then protected as a national historical monument and landscape. History Cistercians The abbey was founded in or about 1182 by Count Gerard of Loon, who sold a part of his lands to raise funds for his participation in the Crusades, and used some of the proceeds to endow a Cistercian monastery for nuns. (Some historians claim that he was forced to do so by Rudolf of Zähringen, the Prince-Bishop of Liège, as a penance for having burnt down the collegiate church of Tongeren). In 1217 the abbey was formally accepted into the Cistercian Order, the first, and also the greatest and wealthiest, women's monastery of the Order in the Low Countries. The nuns referred to themselves as the "noble ladies of the Order of Cîteaux of the County of Loon" (). After Count Gerard was killed during the Third Crusade at the Siege of Acre in 1191, his body was brought back by the same Archbishop Rudolph, who had led an army to the siege. Rudolph reached, though, only as far as Switzerland, dying there on the way home. Gerard was buried in the church of the abbey he had founded, which from then on became the burial place of all the Counts of Loon. This custom continued up to the last Count to die with that title, Dietrich (or Theodoric) of Sponheim (d. 1361), who was refused burial here because he had been excommunicated. In 1366 the County of Loon passed into the possession of the Prince-Bishops of Liège, with whom the nuns succeeded in remaining on good terms. During the 15th century the abbey, like many others, suffered a severe decline, but from around 1500 enjoyed a revival. In the 18th century a total reconstruction was planned, of which the Neo-Classical abbesses' lodgings was built, as well as an English garden, still intact, with exotic trees. The French Revolutionary Army invaded the region in 1795 and annexed it to France. During a policy of
